IMPROVEMENT IN WATER-ELEVATORB.

The Schedule referred to in these Letters Patent and making part of the same.

Io (lll ivlimn et may concern: j

Be it known that LT. 1?'. WILcoX, of Hebron, in the county of Porter, ainl State of Indiana, have invented certain new and useful Iniprovei'nents in Water- Elevators or Apparatus for Raising Water from \Vells; and I do hereby declare the following to-be a full, clear, and exact description of the construction and operation ofthe saine, reference 'heilig had to t-lie accompanying.

drawings, makinga part of this specification, in which- Figure l represents a perspective view of the elcvator. l

Figure 2 represents a vertical section through the same.

Similar letters of reference, where they occur in. the separate figures, denote likeparts iu both of the drawings.

My invention relates to a water-elevator, in which two drums are arranged on one shaft, and always turn with said shaft, and in the saine.` direction with it, each drum having a separate and independent cord or chain that is separately adjustable to lengt-h, while both drums and thc crank-shaft, on whichn they are attached, are caught and held by one or the other of a pair of pawls linke-d together, and working in a common ratchet, as wiil be explained.

To enable others skilled in the art to make and use my invention, I will proceed to describe the saine with bearings B B, on which frame a shaft, C, is'hung,.

which may be turned by a crank, I), at one of its ends.

Upon the shaft C are two drums, E F, which are loose on said shaft., and without other appliances, would not iiirn with the shaft, but which are keyed or locked to. the shaft by a simple mechanism, which canbc removed and replaced in a incluent, asl will be explained.

Each drinn has its own independent cord or chain (l li, ainl each has its own independent bucket G H, thebuckcts being united to their respective cord, rope, or chain by a section of i'lat chaii, c, that will, in winding, always bring the bucket-s in proper position to'the tipping-rodor bar (l, so as to tilt andenipty the contents ofthe bucket into the trough I, whence it runs out through a spout, c.

0n the shaft C, or over it, and fastened to one of the drums lil, is placed a star-ratchet, f, and to the ii'aine A, on opposite sides of the shaft C, there are pivoted pawls q g that ai'e linked together by a link, Iii, properly bent, to clear the drinn and ratchet, and so tha-tas one pawl or dog' is thrown into action with the ratchet f, the other will he thrown out of action, and rice versa, as the buckets which are hung to wind on opposite sides of the drums, should require in their aiternating iillcil and emptied condition.

Flanges il 1I are made on the ends of the drums, to catch and hold the rope or chain as is common.

In one `end of each of the drums E F there is driven, or otherwise fastened, staples, loops, or dead-eyes l, 2, through which, andthrough a hole, 3, in the shaft C, passes a pin, 4, which locks the drinn to the shaft, and causes them to turn together. When, however, this pin is withdrawn, the drum is loose on the shaft, and' can be turned independent of the other drinn, which at times becomes important, as, for instance, in adjusting the length of the ropes, so that the bucket on one will reach the water land till, while the bucket o n the other is caught lby the tipping-rod to be einptied. Y

The descent of one bucket is defined by the ascent of the other bucket, and if the height of the water in the well should change, or one rope become shorter by breaking and uniting it again, the buckets must be adjusted accordingly.

'Ihis attaching and detaching-mechanism, by which the drums shall turn with thc'shaft, and be loosened to adjust the relative lengths of the ropes or chains, is quite important in this simple form of elevator, where, by intricate gearing, two shafts are used, and a drum on cach, alternating buckets can be readily used; but with the simple clank-shaft, and two drums, and ltwo independent ropes or chains, when t-wo buckets are used, there must be a regolatiiig-mechaiiisin to adjust the ropes or chains relatively to each other, and to the surface of the water in the well, and the tipping or delivering point in the curb.

As the buckets alternate, one full and the other empty, the pawls are thrown in and out, so as to hold aga-inst the overpoise of the full one.

Having thus fuliy described my invention,

What I claim therein as new, and desire to secure by Letters Patents, is-

Iii a water-elevator, the combination with a single crank-shaft, C, ofthe two drums E F thereon, each fin'- nish'ed with an independent rope or chain, for raising and lowering an indeiiendent bucket, and always turningr with said shaft, and in the saine direction with it, and secured thereto by staples and pin, or other releasing and adjlisting-mechanism for adjusting the rope or chains to the height of the water in the well, the whole arranged to operate as and the purpose described.

Also, in combination with a single shaft, and the two drums secured thereon by staples and pin, or other releasing and adjlisting-meelianisin, each ot' said drums containing the rope or chain of one of a pair of alternating buckets, the two hinged and linked pawls,

and a single star-ratchet, in which the two pawls work, the whole being arranged to operate in the manner' and for the purpose described.
